, ASSIGNOR TO TI-IE WRAPPING- MACHINE COMPANY OF AMERICA, A CORPORATION OF NEW YORK.

BREAD-YVR-APPING MACHINE.

To n.77 wlw/n 'it in (1,1/ concern.'

Be it known that l. GEORGE R. lVxin), a

citizen of the United States, residing at Hotel Calumet, vest Fifty-seventh street, New VYork city, New York, have invented certain new and useful Improvements in Bread-llvrapping Machines, of which the following is a clear, full, and exact description.

This invention relates to a wrapping machine. particularly to a machine for wrapping bread, and the object is to improve in general the detail structure and combinatie-n of parts of such a machine for producing a bread-wrapping apparatus of superior elliciency and durability.

rl`he main problem in brezul-wrapping machines lies in the difficulty of providing` an apparatus which will at the same time wrap the bread closely and also accommodate itself to loaves of different sizes and irregular shapes. A further consideration in the use of machines of this character is that of economy, and on this account it is desirable to use an extremely cheap wrapping` material such as a very thin paper, preferably waxed. Consequently a machine for handling such paper must be differently designed than one for handling heavy wrapping paper and folding it about rigid articles of uniform size. rl`he present machine therefore is preferably adapted to handle and wrap irregular loaves of bread with a thin wax paper of extreme lightness,

' and furthermore to wrap said paper in such a way that the folded flaps may be secured and sealed in the most efficient way.

iiy invention further consists in a compact design and distribution of the moving parts of my machine whereby unnecessary steps are eliminated and whereby the machine is evenly balanced so as to atl'ect its operations with the least possible movement and thus make it possible for the machine to be speeded to a high degree of eliiciency.

Further objects and advantages of my in vention will become apparent from the following specific description, and the broad scope thereof will be embodied in the appended claims.

in the preferred embodiment of my invention shown in the drawings, Figure 1 is a side elevation of the entire machine; Fig. 2 is a plan ofthe same; Fig. 3 is a horizontal section through line 3-3 Fig. 1; Fig. 4f

is a horizontal section through line 4 4: Fig. 1; Fig. 5 is an end elevation looking from the right of Fig. 1; Fig. G is a. longitudinal section through line (S-G Fig. 2; Fig. 7 is a vertical transverse section through line 7-7 of Fig. 1; Fig. 8 is a detail plan of a paper-gripper; Fig. 9 is a detail section of a heating` shutter; Fig'. 10 is a detail elevation of the cutting device through 10e-10 Fig. 11; Fig. 11 is an enlarged detail of a paper-gripper and the cutting device, showing a section of the cutting device taken through line 1111 Fig. 10; Figs. 12 and 13 are enlarged detail views of the corner end folders in different positions; Fig. 14 is a detail section of said folders in the position shown in Fig. 13; Fig. 15 is an enlarged detail of the bottom end folders in action; Fig. 1G is an enlarged detail of the springholding clamp; Figs. 17 to Q-l inclusive are views showing the various steps of the wrapping operation; Fig. is a detail of the heating shutter operating cam; Fig. 2G is a section through a side-siuipcrting rail along line 2G-QG of Fig. 1; Figs. Q7 to 31 inclusive are views of the various operating cams.

Referring more particularly to the drawings the main frame or base of the machine is indicated by 1, and as shown comprises a lower horizontal platform Q, an upper platform 3, together with vertical standards 74 and top horizontal rails 73 and 73, Intermediate side rails G1 and 61a complete the main supporting elements of the machine, while at the rear are shown supporting brackets 3a and 3b which support at their outward ends let-off mechanism 7, 7fL adapted to feed paper G from a supply roll 6a.

At the lower rear part of the machine and extending transversely thereof is mounted a main cam and driving shaft 9. This shaft is driven through spur gears Lt8 and 12 from a counter-shaft 13, which in turn has belt pulley 14 thereon for receiving power from any convenient source. The cam shaft 9 drives, by means of sprockets S, and connecting chain 10, a friction roll 7, which in turn through meshed gears 7b, 7, drives upper roll 7a for feeding the paper in a continuous web 6 into the machine. The web G is preferably fed fast enough to provide a loop as shown.

The articles to be wrapped such as loaves of bread, are preferably fed to the lower platform Q of the machine along a side tso chute 17. lilaeh loaf as it arrives at the center of this platform is thrust forward upon the head 2i of carrier or lower plunger 22 by means of a feed pusher l5. rIhis feed pusher is slidahly mounted on the lower' platform i2 and reciprocated thereon by link and lever connections lo. 17 to cam Q0 mounted on the main cam shaft t). The link and lever connections consist more particularly. as shown in Figs. l, i3 and 7, of the bell crank lever 17 pi voted at 1S, having one arm connected by link 1G to the rear end of pusher slide ,l5 and the other arm 17a providedv with a pin 17X traveling in a groove lf) of the cam Q0; See `Fig. Q7.

lefore the bread carried upwardly upon plunger head Q1. a wrapper carried across the subsequent path of movement of the bread by the followingv mechanism. Slidably mounted in the ,side rails (il and Gt by any suitable key connection is a crosshead 3l (see Figs. (l and ll) upon which is carried, preferably two lsets of paper-grip pers 32 respectively (see Fig. t). Each paper-gripping device as shown in Figs. 8 and l1. consists of an upper stationary jaw 32 and a lower pivoted jaw 231i which is provided with a coil spring 23S tendiner to normally keep it closed upon the upper jaw and having a tail "u adapted to engage with 51") suitable wedges 39 for opening the grippers at `the proper time. rihe cross-head 3l. and the gripper-s carried thereby are caused to travel. back and forth in their slides by means of connections Controlled by cam groove 25%" of cam 2.7 mounted on. the main cani shaft l). Vthese coimeetions comprise a cam rod 2S forked at 28a to embrace shaft 9. and having a pin 28X traveling in said cam groove Qd" of cam 2T (see Figs. l, t3, 7 and rthe outer end of rod QS is connected to an arm Q9@ fixed to a sleeve 29h loosely mounted upon a shaft Llt. The sleeve QW. as shown in Fig. 5, has extending upwardly from each end, arms 29 and 29a, which in turn are connected to the crosshead l 1 h v links i3() and 30 respectively.

'the means for opening' and closing the papergrippers at the proper times so that in their rearward position they will open to grip a wrapper and carry it along the inachine to a forward position and there open. are as follows. eneath each side rail G1 and Gl"L respectively is slidably mounted wedge carriers et@ and 40 respectively. vleepers or Ushaped straps il@ and #t0n Cured to the side rails (il and til respectively provide the supporting bearings for the wedge carriers et() and l-OL (see Fig. QG). As shown in llig. ti, each wedge carrier #t0 hasv at separated points thereon wedges 39 and ll with their inclines facing oppesitely so as to aetuate the papeigrippers at ea ,ih end of their travel. As shown in Fig. 1l. the wedge 39 moving relatively to the tail of l l A i the paper-gripper, causes the saine to open or close under the force of its spring 3S, depending on the direction of relative movement. The movement of the wedge slides l0 and 40 is controlled by cani groove 4.9 upon one face of gear llS through suitable connections, now to be described. A cam lever fl? having a forked end 4T embraces shaft l) upon the outer face of gear 41:8 and has a pin 77X traveling in eain groove it!) of said gar face (see Fig. 3l). rllhe outer end of rod 47 is connected by crank to shaft ft-t mounted .in bearings of the main frame. The shaft ft has fixed thereto. one at. each side of the main frame, arms ft?) and t3, which in turn are connected to slides At() and `il-O through linksl and 42, TYlledges 39 and -UL are operated so as to open the papciegrippers previous to their arri val at the rear of the machine adjacent the cutting device, as shown in Fig. ll, and then immediately pass from under the tail 35 of said grippers so as to allow them to close upon the paper. ledges il and il. at the other end of the paper-gripper travel, likewise have a converse double movement, first opening the grippers to release the paper, and then allowingl the same to close during their rearward travel for another sheet.

The mechanism for cutting the continuous web G into measured wrapper lengths comprises a knife head 50 carrying a knife 5l therein adapted to cooperate with groove knife block (see Fig. 1l). As

shown also in Fig. 10, the knife head 5G prel'erably carries a yielding presser-block 54A, which is slotted to allow the passage of the knife 51 therethrough and which is meunted on pins 52 sliding in sockets of head 50. Coil springs 5?) embracing rods 52 normally keep the presser blockrin its outward position. The function of this presser-block is to engage the paper and securely hold it against the opposed knife block 55 during the cutting of the paper. whereby an even uniform cut is obtained. Moreover lower plunger head 2t and upper plunger head GS are preferably operated as will be described to clamp the bread and interposed wrapper Hrmly during the action ot' the cutting` knife 5l. Tension springs Si, 3.7, mounted on support 3G and adapted to bear frictionally upon the paper during its travel may also be provided if desired for ehe-cking the overtravel of said paper. .fr paper guide consisting of a plate 33 secured to the main frame is provided for guiding the paper in its travel from the supply roll to the cutting mechanism and grippers. rlhe knife head 50 is given its reciprocating vertical movemnt from the peripheral cam edge of cam 27 mounted on the main shaft 9 (see Figs. 6 and 22). A eam lever 57 pivoted at 59 on the main frame has a roll 58 in Contact with the peblades riphery of cam 27, and at its outer end is connected by a link 5S to the knife head 50. A. coiled spring 59 tends to keep said lever 57 down and roll in conta '.t with cam edge G0 (see Figs. 1, G and As the wrappingl paper is brought to position above the lower plunger-head 21, this plunger QQ is raised to carry the bread and wrapper through orifice of the upper platform 3. and said low-er plunger 22 is reciprocated as follows. A cam lever Q-l is pivoted at upon the main frame and carries the roller Q-l-X bearing on cam 26 mounted on main cam shaft 9 (see Figs. 7 and 2S). The outer end of lever Qt connected by link 23 with plunger rod 2Q. coil spring 22a surrounding said rod tends to keep the same in its lower position and the roll 94?; in contact with its cam surface.

Cooperating with the head Q1 of bottom plunger is a head G2 yieldingly mounted in a top plunger (33 which is vertically reciprocatcd so as to press the wrapper against the top of the bread and keep it in contact therewith during the upward travel of said bread and wrapper through the orifice of upper platform Head GQ has a stem QT-'l within a socket of plunger (if-5 and normally and yieldingly held outwardly by spring 975. rEhe top plunger rod (323 has bearings in a transverse top piece T2 secured to the upper rails .3 and 75. rllhe plunger (323 is given its vertical movement from cam groove GS (see Fig. lBO) on cam (3T mounted on the main cam shaft 9 by means of the following connections. cam rod GG is forked at. its lower end to embrace the shaft 9. and has a pin 66X traveling in groove GS of said ca'm GT. rfhe upper end of the rod 6G is connected to a swinging bracket G t having arms G-l-b, Gt and (S-tc, embracing and looselv mounted upon shaft G5. Arm (3st@ of the bracket extenoed into arm (-l-f, which in turn is connected by a link 6% to the upper end of plunger rod GP).

The upper platform B has a centrally-disposed orifice in line with the plunger heads 21 and (32, which orifice has side valls T5 adapted to turn side portions of the wrapper downwardly against the sides of the bread when the same is carried therethrough, as shown in dotted lines in Fig. 1Q. Leaf springs To are also preferably mounted upon the side walls To' so as to frictionally engage the side of the wrapper and cause them to hug closely the sides of the bread duringthe travel therethrough and vet yield readily to any irregularities of different loaves.

The next operation is to fold down end portions of the wrapper against the ends of the article, and this is accomplished by means of vertically reciprocated end folding blades 7T, TS, 77u, 7811. These end folding` are moved simultaneously against the ends of the article, as shown in Figs. 15 and 1T, and are controlled from cam groove S6 upon the inner face of gear 418 (see Fig. 31) by the following mechanism: A. cam rod S has a lower forked end with a pin engaging groove 86, and its upper end is connected to a crank 8O fixed to the shaft (35 mounted in bearings of the main frame. .also fixed to this shaft 65, one at each side of the machine, are arms and SQ which have a pin and slot connection at their outer ends with the supports S1 and Si of their respective end folding blades. rEhe supports S1 and S1a have sliding bearings through the top cross-piece T2 as shown in Fig. 2. Fach end folder, as shown more clearly in Figs. 153 and 17, consists of a pair of spaced blades such as 7T and 7S. rlChe outer blade 7S is preferably7 a little longer than the inner blade 'T7 so that it engages the outer end portion of the wrapper slightly before the inner portion is engaged, and therefore turns down the outer portion and starts the fold before the inner blade 7T strikes the paper. This action tends to lead the fold properly, and is particularly desirable witl a thin flimsy wrapper.

Mounted in bearings at each side of the machine and extending long-itudinallj,T thereof are upper and lower horizontal cam shafts 99, 95, 100, 9G. The cam shafts 95 and 99 are driven from a vertical driving shaft by mraus of beveled gears 93, 9i, 9T and 98 respectively, as shown in Figs. 1 and 7. The vertical shaft 90 is driven from the main cam shaft 9 by beveled gearsl 93 and 92. Similarly at the other side of the machine a vertical shaft 91 driven by beveled gears 10Ga and 9b have connections to lower horizontal shaft- 9G through beveled gears 101 and 10G (see Fig. 7), and connections to the upper horizontal shaft through beveled gears Q00 and 201. The horizontal cam shafts thus symmetrically disposed on each side of the machine furnish controlling means whereby the different folding blades may be easily and efficiently operated with simple and direct connections.

After the end folds have been made l,and preferably while the end folding blades TT and 7T are in their engaging position as shown in Fig. 19, the corner folds are made. It should be here remarked that when the sides and ends of the wrapper, as heretofore described. are both folded down against the article, cocked portions of the wrapper are left outstanding from the corner edges of the bread, and in order to make a neat and secure end wrapping, these cocked portions should be folded against the ends of the article, preferably one over the other as shown in Figs. 1st and 20, and also at a high point upon the end of the article so as to bring their overlapping ends as square with one another as possible. In order to accomtionally driven along the top of the platform in the direction shown by arrow in Figs. 22 and 23.

The bread being now completely wrapped, it is ejected from between the supporting clamps 117 and 1172L by delivery pusher 13S as shown in Fig. 23. The delivery pusher 1.38 is carried on a slide 137 mounted directly above folding blade 131, and said slide is actuated by a lever 135 connected thereto b y link 13G (see Figs. G and 7). Lever 135 is pivotally mounted in a bearing 131, and has an end 133 provided with a pin engaging groove in barrel cam 132, fixed to the rear end of the upper horizontal shaft 100. The wrapped loaves of bread are thus delivered successively and in contact along upper platform 3, as shown in Fig. 2, and the forward end of the platform 3 is provided with a heating plate 145, shown clearly in Fig, 6, which acts by melting the waxed or other previously prepared paper, to seal the under flaps of the wrapped articles as they rub along in contact therewith. The plates 145 may be heated in any suitable manner, as by means of gas jets let-G shown in Fig. G. 1t should be here noted that the under-side of bread is often irregular or concave in shape due to shrinkage, and that by first tucking end portions of the wrapper beneath the article and finally overlapping the side portions thereon, the last two side flaps are thus sealed to each other and the space between them and the bottom of the bread is stuffed by the tucked-under end portions. It will also be observed that the present machine is designed to handle the bread loaf during the wrapping operations entirely upon this bottom side, a great advantage in the operation of such machines, since this is usually the only regular side of a bread loaf.

Usually the sealing of the bottom flaps is sufficient to secure the wrapper in place, but I have also provided additional means which may be employed, if desired, for sealing as well, the end folds of the wrapper upon each other to more securely bind the same upon the loaf. Such means are provided by swinging heating shutters 147 and 14W (see Figs. 1 and G), which may be heated in any suitable way, as by electricity as shown in Fig. 9, and heating shutters are supported from shafts 11S, 118n rocking on the main frame. Arms 149,149 extending from these shafts have rollers engaging operating cams 150, 150, in turn fixed to upper horizontal cam shafts 100 and 99, respectively. The cams 150, 150 close the heating shutters upon the loaves while a spring 175 is provided to separate said shutters. In this way the end flaps are sealed by both pressure and heat. Beyond the heating shutters are mounted on fixed arms 250, 250LL leaf springs 251, 251e, which are adapted to bear with yielding pressure upon the ends of the wrapped package as it passes therethrough so as to more effectually seal said ends.

Recounting briefly the several operations of the machine as described, the bread and wrapper are first fed between the vertically reciprocating plungers and while firmly clamped between said plunger heads the wrapper sheet is severed. The loaf with the wrapper above it is then carried from the lower platform to the upper platform, whereby side portions of the wrapper are folded downwardly against the loaf as shown in Fig. 12. Vertical end folders then descend at each end of the loaf shown in Figs. 17, 18, and fold end portions of the wrapper against the loaf. Before these end folders are withdrawn, Fig. 19, swinging corner folders, (Figs. 12, 13), two at each end of the article, act successively (Fie. 14) in turning over the outstanding corners of the wrapper upon the end of the article, as shown in Figs. 19 and 20. Next end clamps support the loaf while horizontally movable end folders tuck the lower end portions of the wrapper beneath the article, as shown in F ig. 15. The final wrapping operations then take place by folding depending side portions of the wrapper in successive flaps on the bottom of the article as shown in Figs. 21 and 22. The wrapped article is then pushed along the surface of upper platform 3 as shown in Fig. 23, and passes along this platform whereby the end and bottom flaps are securely sealed by the heating means described.
